Abstract: Methods for production of automobile airbags with decreased air leakage and an increased duration of their inflated state, as well as airbags produced in accordance with these methods are provided.

Abstract: A woven fabric comprising spun synthetic polyamide yarn woven in the warp direction and weft direction wherein the polyamide yarn in the woven fabric exhibits a formic acid relative viscosity of at least 60, a halide:copper molar ratio of at least 2.0 and a sodium content of no more than 25 ppm, and wherein the woven fabric exhibits a melt-through resistance at 450° C. of least 2.10 seconds. The invention also provides an airbag made the woven fabric, as well as a method of making the same.

Abstract: A method for producing a woven fabric comprises weaving fibers in a warp direction and a weft direction to form a fabric having a top surface and a bottom surface, wherein the warp fibers and weft fibers each comprises one or more filaments of a synthetic polymer having substantially uniform cross-sectional composition. At least a portion of the filaments in the fibers on the top and/or bottom surface of the fabric are then fused together in the presence of a heat transfer liquid or vapor added during the fusing step or added in a prior step of the fabric production process and retained by the filaments. The fusing step produces a treated fabric having a tensile strength in both the warp and weft directions of 1000 N or greater and having, in the absence of any coating, a static air permeability (SAP) of 3 l/dm2/min or lower.

Abstract: An uncoated woven fabric of yarn formed from synthetic fibers woven in the warp direction and weft direction to form a top surface and a bottom surface wherein at least a portion of the yarn on the top surface or at least a portion of the yarn on the bottom surface has fibers with a permanently modified cross-section and that are fused together is provided. Methods for production and use of this fabric in application to products such as automobile airbags, sailcloths, inflatable slides, temporary shelters, tents, ducts, coverings and printed media are also provided.
